in 2010,the worlds population was about 6.8 billion 。more than three billion people live in asia now 。that's almost half of the world's population .china has the largest population in the world libe in china .because of the large population ,there is less living space for each fimily ,and it's difficult for lots of people to find jobs.the large population also causes many other difficulties for the whole nation. for the example, we are short of energy and water。 most cities are more crowded than before,and the traffic is much heavier.the large population has become a servious problem。
so far our goverment has taken many measures to contrd the population one is known as the one-child policy ,it has worked well in controling china's population thanks to the policy ,china is developing quickly and people's living conditions are improving rapidly,however, the population problem is still serious in china,we still have a long way to go.
